Precision study of few-electron, high-Z ions is a privileged field for probing high-field, bound-state quantum electrodynamics (BSQED). However, the accuracy of such tests is plagued by nuclear uncertainties, which are often larger than the BSQED effects under investigation. We propose an alternative method with exotic atoms and show that transitions may be found between circular Rydberg states where nuclear contributions are vanishing while BSQED effects remain large. When probed with newly available quantum sensing detectors, these systems offer gains in sensitivity of 1 to 2 orders of magnitude, while the mean electric field largely exceeds the Schwinger limit.

Article Synopsis
- Strong coupling between nanocavities and single excitons at room temperature is crucial for studying cavity quantum electrodynamics, influenced by factors like light confinement and electric field orientation.
- A hybrid cavity design combining a one-dimensional photonic crystal and plasmonic nanocavity enhances quality factor, minimizes mode volume, and allows control of electric field direction using Bloch surface waves.
- Achieving a Rabi splitting of around 186 meV with only 8 excitons involved marks a significant advance, producing an effective coupling strength of 17.6 meV per exciton, which is nearly double the previously reported values for TMD-based systems.
Gravitational Metrological Triangle.
Phys Rev Lett
December 2024
Fundamentale Physik für Metrologie FPM, Physikalisch-Technische Bundesanstalt PTB, Bundesallee 100, 38116 Braunschweig, Germany.
Motivated by the similarity of the mathematical structure of Einstein's general relativity in its weak field limit and of Maxwell's theory of electrodynamics it is shown that there are gravitational analogs of the Josephson effect and the quantum Hall effect. These effects can be combined to derive a gravitational analogue of the electric quantum metrological triangle. The gravitational quantum metrological triangle may have applications in metrology and could be used to investigate the relation of the Planck constant to fundamental particle masses.

High-harmonic generation (HHG) is a nonlinear process in which a material sample is irradiated by intense laser pulses, causing the emission of high harmonics of incident light. HHG has historically been explained by theories employing a classical electromagnetic field, successfully capturing its spectral and temporal characteristics. However, recent research indicates that quantum-optical effects naturally exist or can be artificially induced in HHG, such as entanglement between emitted harmonics.

Multipolar quantum optics deals with the interaction of light with matter as a many-body bound system of charged particles where the coupling to electromagnetic fields is in terms of the multipolar electric polarization and magnetization. We describe two transformations applied to the conventional non-relativistic formalism, namely a gauge transformation applied directly to the fields at the Lagrangian stage and a unitary transformation applied to the old Hamiltonian. We show how such transformations lead to the same Power-Zienau-Woolley (PZW) formulation of the quantum electrodynamics (QED) of an overall electrically neutral many-body bound system of charges, including the internal motion as well as the gross dynamics of the centre of mass.

Room-temperature cavity quantum electrodynamics with molecular materials in optical cavities offers exciting prospects for controlling electronic, nuclear and photonic degrees of freedom for applications in physics, chemistry and materials science. However, achieving strong coupling with molecular ensembles typically requires high molecular densities and substantial electromagnetic-field confinement. These conditions usually involve a significant degree of molecular disorder and a highly structured photonic density of states.
